STRDPPING DEVICE FOR SAFETY-RAZOR BLADES.

Application filed July 9, 1914i. Serial No. @tQfllfi.

To all whom it may concern:

Be it known that l[, HUGO Honniomof Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Stropping Devices for Safety-Razor Blades, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to stropping devices for safety razor blades and an object thereof is to provide a construction by which a safety razor blade may be secured and held in proper position to have its edge or edges stropped on an ordinary strop, the construction being such that the securing means for the clamping members may readily move over the strop without scratching or cutting the latter.

To these and other ends, the invention consists in certainparts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claim.

In the drawings: Figure 1 is a plan view of the stropping device with a double edged blade therein; Fig. 2 is an enlarged view showing the clamping members in open position; Fig. 3 is a still larger view showing the clamping members held together by the securing device, the parts being in longitudinal section on the line a-w, Fig. 1; Fig. 4 is a section on the line 6-1), of Fig. 1; and Fig. 5 is a perspective view of the securing device. v

In the illustrated embodiment of the invention, there is employed a handle 1 made in any suitable manner and having a clamping member 2 extending in the direction of the length of the handle 'and preferably rigid and integral therewith. There may also be provided a movable, clamping member 3 which preferably'is pivoted at 4: to the handle at a point near the inner end of the rigid clamping member 2. Both of these" clamping members are in the form of plates having their opposed faces flat and their outer faces curved transversely. From the flat face of the rigid clamping member, two posts 5. extend, these posts being preferably in the form of semicircles in cross section and having their curved faces disposed toward each other. The movable clamping plate has two openings corresponding to the cross sections of the posts so as to receive the posts when a blade, such as a double edged the pockets 11. vents the fastening blade with two circular openings, is fitted over said posts.

A feature of this invention is the provision of a fastening or securing device which will hold the clamping members together at their free ends while at the same time not interfering with the passage or movement of the device over a strop. This securing or fastening device is in the form of a bifurcated member 7 having its two arms 8 formed at their free ends with opposed curved or beveled portions 9 while theoute'r faces of said arms are flat. The bifurcated member may also be provided with notches 10 forming shoulders which permit the fin-.

gers of a user to readily remove the fastener from the clamping members or facilitate the fitting of the fastener to such members. The inner faces of the bifurcated fastening or securing device cooperate with the outer faces of the clamps near the free ends of the latter and hold the clamps upon the blade 6. To the end that the outer faces 8 of the securing or fastening device 7 will lie flush with the outer faces of the clamping members, the outer faces of the clamping members are provided with pockets or recesses 11 which conform substantially to the proximate faces of the arms 8 of the fastening or securing device so that said arms are received within This arrangement also predevice from being shifted laterally on the clamping members during the action of stropping.

In the use of the device, a double edged or other blade having two circular openings is fitted over the post 5 after which. the clamping plate 3 is moved to clamp the blade against the clamping member 2. The fastening device then has its arms 8 introduced into the pockets 11 so that the clamping members are held in clamping position. The blade may now be moved back and forth over the strop and the fastening device is so mounted that it does not present any sharp edges or projections which would interfere with the stropping action. The pockets which receive the fastening device not only serve to make the latter flush with the outer faces ofthe clamping members, but they prevent the lateral movement of the fastening device on the clamping members. The semicircular posts prevent movement of the blade between the clamping members and at the same time make it easy to fit the blade of the posts.

Having thus described my invention, What I claim is:

A stropping device comprising a handle,

. a pear of blade clamping members supported at one end of the handle and having their longitudinal axes extending in the direction of the length of the handle to receive a blade between; them, the ,free' ends of the blade clamping members each being provided with a pocketon its oliter face opening at the outer'end of the member and of less Width than the member, and a separable bifurcated fastening device extending around the free ends of the clamping members to exthe shopping action.
